The title is not clear enough. One way of understanding is to choose six different flowers to form a group, which should be (10 * 9 * 8 * 7 * 6 * 5)/(6 * 5 * 4 * 3 * 2 *1) = (10 * 9 * 8 *. If it is understood that six pots of flowers are selected for grouping, and the pots can be the same or different, it should be the method of 10 6 = 1000000.
